Title: Pressure accumulation type sprayer
Inventor: SAITOU TADAO
IPC: B05B11/00
Filed: 1979-03-27
Abstract: PURPOSE:To obtain the accumulation type sprayer of easy assembling and less troubles by reducing the number of constituting parts. CONSTITUTION:Six members of a sprayer body 1, spray head 20, fitting member 30, piston member 40, sucking-up pipe 50 and spring 60 are made constituting parts. A bar-form valve body 33 enters the inside of a suction valve hole 9 to close the valve, then the pressure in the pressure accumulation chamber consisting of the inside of both large and small diameter cylinders 31, 6 and piston member 40 increases gradually. Then, the piston member 40 descends owing to the diameter difference of the cylinders 31, 6, causing a discharge valve 36 to open to exhaust compressed air through nozzle orifice 36. When the piston 42 reaches a longitudinal groove 11a, the passage to the through-hole 12 is formed and the high-pressure state in the pressure accumulation chamber is eliminated so that the member 40 closes the discharge valve. When a spray head 20 is pushed in this state, the members 40, 30 and the spray head 20 ascend, by which the liquid of the vessel 70 is sucked. By the next depression of the spray head, the pressure liquid is sprayed through the nozzle orifice 24.

Title: Trouble detecting circuit for load driver
Inventor: SAKAI NOBUO
IPC: H03K17/08
Filed: 1980-03-24
Abstract: PURPOSE:To improve the reliability of a load driver by detecting the fault of its contact means direct by providing an auxiliary contact means of providing the same on-off operaion with the contact means by a binary signal, and a means of detecting a difference in potential from the contact means at on terminal. CONSTITUTION:When switching trasistor TR performing on-off operation by a binary signal from CPU of a controller body and auxiliary switching transistor TRS are both in normal operation, the collectors of TR and TRS are held at the same potential and no current flows through light emitting diode PD1 of detecting means DM, which does not emit light. If TR is in trouble and stays turning off, the outputting of signal ''1'' from CPU holds the collector potential of TR higher than that of TRS, and a current flows to PD1, which turns on. When the trouble of TR originates from a short circuit, the collector potential of TRS rises and a current flows to PD1, which turns on. The trouble of TRS is similarly detected by DM. Thus, the reliability of the driver is improved.

Filed: 1981-03-13
Abstract: PURPOSE:To exactly start a lens motor of an auto-focusing camera, by making a large current flow so that the motor overcomes a load resistance and is started when it starts. CONSTITUTION:When an image forms an image on the photodetecting surface of a self-scanning type photoelectric element 3 through a lens 2, the photoelectric element 3 forms a photodetecting signal, and applies it to an automatic focus controlling circuit 5.

Title: Semiconductor laser device
Inventor: HIRONAKA MISAO
IPC: H01S5/00
Filed: 1987-02-18
Abstract: PURPOSE:To obtain a semiconductor laser device with small astigmatism and excellent noise characteristics, by setting the length of a current blocking layer in the direction of a resonator as the length wherein loss exceeds gain and laser oscillation does not occur, said current blocking layer being arranged outside a groove perpendicular to the direction of the cavity. CONSTITUTION:A P-type GaAs semiconductor substrate 1 is provided with a groove 9. In the groove 9, an N-type AlxGa1-xAs current blocking layer 9a is formed, on which a P-type AlyGa1-yAs lower clad layer 10a is arranged. Outside the groove 9, an N-type AlxGa1-xAs current blocking layer 9b is formed, on which a P-type AlyGa1-yAs lower clad layer 10b is arranged. As the clad layer 10b is thinner than the clad layer 10b, a light oozing out of an AlzGa1-zAs active layer 5 is liable to be absorbed by the outer part of the groove 9 on the P-type GaAs semiconductor substrate 1 and the N-type AlxGa1-xAs current blocking layer 9b. Therefore, by increasing the light absorption amount of this part, the effective reflectivity distribution in the transversal direction is intensified, and the laser light confinement efficiency is increased. Thereby, astigmatism can be reduced without losing excellent noise characteristics.

Title: Fuel injection pump for diesel engine
Inventor: MINAMI MINORU
IPC: F02D41/04
Filed: 1995-02-24
Abstract: PURPOSE: To obtain an injection amount characteristic in accordance with a rotational speed, so that worsening running performance can be prevented particularly at an upward slope running time. CONSTITUTION: A high degree compensating mechanism 47 is constituted by a bellows 48, push rod 49 and a connecting pin 50 with its one end itself into contact with a tapered surface 49a of the push rod 49 to extend the other end toward an upper part of an adjusting lever 32. At high land running time with atmospheric pressure lowered down, the connecting pin 50 is moved, and even when an accelerator pedal is stepped in to a maximum limit, the adjusting lever 32 comes into contact with the other end of the connecting pin 50, to obstruct turning. Consequently, turning amount of the adjusting lever 32 is not increased to a permissible maximum value, to provide a partial loaded condition.  Accordingly, a characteristic of injection amount relating to an engine speed comes to be a partial load characteristic, so as to provide a characteristic that the injection amount is gradually decreased in accordance with being at high speed time.

Filed: 1989-02-18
Abstract: PURPOSE:To transmit a digital signal at high speed by providing two diodes serially connected between a TLL output terminal and the base of an emitter follower transistor, and preventing the saturation of the output transistor when an output terminal is at a low level. CONSTITUTION:When transistors 9 and 10 are cut off and transistors 7 and 8 go to energizing state, the voltage level of an output terminal 6 is made low. At such a time, when the collector voltage of the transistor 7 is lowered and the joining of the base and collector is regular bias, two diodes 18 and 19 connected between the collector of the transistor 7 and the base of the transistor 8 go to the energizing state and the base current of the transistor 8 is decreased. As a result, the collector voltage of the transistor 7 is lowered and the base current to be a saturated state is decreased. Then, the saturated state is prevented. Accordingly, the storage of carriers is not generated in the base of the transistor 7 and the transistor can be speedily changed from the energizing state to the cut-off state.

Abstract: PURPOSE:To eliminate intervention between a photosensitive drum and a developing sleeve by releasing the abutting of the photosensitive drum on the developing sleeve when a front case opens a fixed angle or more. CONSTITUTION:When a water toner recovering unit enters a printer main body, a 1st development supporting cam engaging shaft 40b hits the upper part of a cam 21 and rotates in a direction E to release the engagement of the cam 21 and a cam 22. The cam 22 rotates in a direction F, while a cam 23 moves in a direction G. Accordingly, force pulling a developing device 4 in the direction F disappears, and the developing sleeve 30 is brought into contact with the photosensitive drum 1. The cam 22 engages with an engaging shaft 40a. As the toner recovering units is pulled out, the cam 22 engages with the shaft 40a. The cam 23 is pulled in the opposite direction to the direction G, and the device 4 turns in the direction F to release the contact of the developing sleeve 30 with the drum 1. The cam 21 is energized in the opposite direction to the direction E, and prevents the return of the cam 22 to fix the position of the sleeve 30. Thus, the intervention between the drum and the sleeve can be eliminated.
